摘　　要：基于FLAC软件对采空区下煤层巷道支护方式进行仿真分析,分别建立包含和不含支护系统的两个模型,计算与分析支护系统对围岩应力的分布情况。研究表明,安装支护系统可有效缓解巷道周围岩层压力分布情况,压力分布更加区域均布,特别是对于巷道周围较近的塑性区岩层改善较为明显,同时,采用支护系统后,围岩的应力分布状况有了明显改善,生产效率得到了显著提高。Based on the simulation analysis of coal seam roadway support mode under goaf by FLAC software, two models including and without supporting system are established, and the calculation results show the distribution of surrounding rock stress by supporting system. The research shows that the installation of support system can effectively relieve the pressure distribution of rock strata around the roadway, and the pressure distribution is more evenly distributed in the area, especially for the relatively close plastic zone around the roadway. At the same time, the stress distribution of surrounding rock is obviously improved after the use of support system, and the production efficiency is improved significantly.
